STEAM FEED-COOKER.

SPECIFICATION forming part of Letters Patent No. 387,525, dated August '7, 1888.

Application filed January 26, 1888. Serial No. 261,937. (No model.)

To all whom it may concern.-

Be it known that we, JAMES W. MARTIN and CLAUS H. REINHOLDT, citizens of the United States, residing at Manning, in the county of Carroll and State of Iowa, have invented certain new and useful Improvements in Steam Feed-Cookers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to that class of devices for steaming food in which the steam is generated and conveyed by pipes to feed-receptacles, into which it escapes; and our invention has for its object simplicity of construction,

combined with excellence of operation and increased durability of parts and facilities for performing work.

With these ends in view our invention consists in the novel construction and combination of parts, more fully described hereinafter, and pointed out in the claims.

In the accompanying drawings, Figure l represents a side elevation of our complete device, part of the outer shell being removed to show the internal construction; and'Fig. 2, a plan with the top crown-plate removed.

The reference-letter a indicates the base portion, which is given a rectangular form in horizontal cross-section. The sides are sloping to prevent overturning. rlhe front is'provided with a hinged door, n, for the removal of ashes from beneath the grate m, and the rear is provided with a draft-register, n. The heatingchamber shell g is provided with a iiange, i', which rests upon the base a. The collar h encircles the bottom of the shell, and is provided with a iiange, z', which is drawn down upon the shell-iiange z" and securely fastened to the base by the bolts or rivets j. The upper end ofthe shell is joined to the crown-plate Z in a like manner; but a packing of asbestus, s, is interposed, and the crown-plate is provided with a ange, 7c, which telescopes with the npper end of the shell g for the purpose of perfecting a gas-tight joint. The boiler q is located in the center ofthe heating-chamber, and its upper end is joined to the crown-plate in the same manner as the shell g. rlhe lower end of the boiler is seated upon a shelf, u, and is joined thereto by a fiange, k', and collar h,

forming a telescopic connection in the same manner as its upper end is joined to the crownplate. The shelf closes the lower rear half, q', of the heating-chamber, as will be observed in Fig. 2. The crown-plate and sheli` are thus made to serve the double purpose of end plates and supports for the boiler.

A pair of partitions, y, are placed upon diametrieally-opposite sides of the boiler, between the shell g and the boiler. They extend from the bottom -of the boiler upward almost to the top of the chamber for the purpose of directing the heat ofthe fire over the front half and down over the back of the boiler to the outlet or smoke pipe o, thereby deriving the full benefit of the fire.

z represents the outlet-pipe, which is provided with a cock, a', for the purpose of drawing the water off at will. Two short pipes, b b', located one above the other and communieating with the boiler, are provided upon thci r outer extremities with cocks c e', whereby the height of the water in the boiler may be easily determined. The steam-outlet orifice d is located in the center of the crown-plate, and is provided with a T-pipe, c. A pair of pipes, f,"extend laterally from this T and thence downwardly into the feed-receptacles. rllheir escape-nozzles o' may be provided with any suitable steam-spreading devices in order to cool; the food equally as well at the sides of the barrel as in the center. At the elbow g' of the T an ordinary pop-valve, h, is placed as a safeguard against accident.

The construction of our device having been set forth, we will now describe its operation.

The products of combustion of the iire are made to pass around the front part of the boiler, between the boiler and the outer shell, g, by means of the partitions. They then pass down over the back side of the boiler, and thence out of the smoke-pipe locatedj ust above the bottom of the boiler. The products Ofcombustion are thus made to pass completely around and envelop the boiler before passing out. The steam passes out at the escape-oriiice in the crown-plate, thence to the T, where it is divided and conveyed off at right angles, and thence through pipes f to the escapenozzles, where it passes into the feed being cooked.

Among the advantages of our invention are those of exceeding simplicity, great strength, ease of operation, the quickness with which it can be repaired, the cheapncss of manufacture, and the perfect safety with which it can be used.

It is evident that many slight changes in material and arrangement of parts might be resorted to without departing from the spirit of our invention. Therefore we wish it understood that we do not limit ourselves to the precise construction herein shown and described, but consider ourselves entitled to all such va riations as come within the scope ol' our in- Vention.

Having thus described our invention, what we claini as new, and desire to secure by Letters Patent, is-

l. In a feedcooker, a heating-chamber and a boiler therein having llanged ends provided with collars, in combination with a crownplate and shelf attached to the boiler in such a manner as to form end plates and supports for the boiler, substantially as described.

2. In a feed-cooker, a boiler and a surrounding shell forming,r the heatingchalnber, said boiler and shell being provided with flanges and ilanged collars, in combination with a crown-plate to which said collars are attached, whereby said plate is made to close the upper end of the boiler and heating-chamber, for the purpose and in the manner substantially as described.

3. In a feed-cooker, a fire-chamber shell and boiler having` the upper ends provided with flanges, in combination with a crown-plate having downwardly-extending` flanges fitting" within the ends of said shell and boiler, and collars provided with flanges, whereby the ends of the boiler and shell are closed, substantially as described.

et. In a feed-cooker, a boiler located in the upper part of the fire-cha1nber, and a shelfsupporting said boiler, said shelf being arranged to form the bottom of the boiler, in combination with partitions located upon dialnetrically-opposite sides of the boiler, substantially as described.

5. In a feed-cooker, a boiler located in the top of the heating-chamber and having its upper end plate arranged to close the top of said chamber, in combination with partitions located upon diametricallyopposite sides 0l' the boiler, and a bracket 0r shelf arranged to forni the lower end plate of the boiler and to close the space behind the saine, substantially as described.

6. In a feed-cooker, a boiler located above the lire-chamber, the upper end of said boiler being arranged to close the top of said cham ber, in combination with partitions at the sides and a shelf or bracket at the lower part ol the boiler, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
